I'm not 3b but I do know that curl cremes under a gooey gel helps. The curl creme helps with clumping and the gooey gel keeps larger clumps together. Not raking products in helps too. Apply products to not dripping but very wet hair will help with clumping.
Oh also some find brushing and then adding product in helps. It's experimenting that finds what works for you that's fun!

Most 3bs are naturally smaller clumped it seems like. I happen to like the look myself. I'd take the tighter curls
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
